本文对具有冷次级发射阴极的磁控管辅助阴极的特性进行了理论研究。研究了从辅助阴极提供空间电荷限制发射的不同方法，以消除发射电流的温度依赖性。提出了新的辅助阴极设计，以提供更好的发射电流的稳定性相对于温度的变化，相比，目前使用的阴极在spatialharmonic毫米波长磁控管。
A theoretical study of properties of the auxiliary cathode of magnetrons with cold secondary-emission cathodes is performed. Different methods of providing a spatial-charge limited emission from the auxiliary cathode are studied in order to eliminate the temperature dependence of the emission current. New designs of the auxiliary cathode are proposed to provide a better emission current stability with respect to temperature variations, as compared to the currently used cathodes in spatialharmonic mm-wavelength magnetrons.
